A musical rejection of reality

As seen in the opening scenes of Joker 2 In the first trailer, Arthur Fleck is still being held in Arkham. As he is escorted through the halls of the psychiatric facility by two guards, Joker sees Harley Quinn in another room, where she is participating in what appears to be musical group therapy. A voice-over comment is also made on the use of music and its intended healing effects:

“We use music to make us whole. To reconcile the fractures within ourselves.”

Instead, it looks like Harley and Arthur will end up using music to motivate each other through their mental health challenges through a shared singing performance. This is evident in the various shots in the new trailer, which feature many Joker and Harley dancing and singing on stages and sets. This includes the duo dancing on the roof of the remarkable Hotel Arkham (rather than the institution it actually is).
